Positive experience - 3 times verifying
I've used their service several times for 1 time verification tasks (50k emails) They are the cheapest price I've been able to find on the internet. The dashboard is user friendly and is very clear telling you how much time it will take. Deliverability after cleaning is 98.5-99.5% I recommend breaking your email lists into smaller chunks for faster processing -- 3 groups is max at one time.
